Recombinant human FBXO45 protein is a genetically engineered form of the F-box protein 45. a key component of the Skp1-Cul1-F-box (SCF) E3 ubiquitin ligase complex. As an F-box protein, FBXO45 contains an F-box domain that mediates interactions with SKP1. linking substrate recognition to ubiquitination machinery. FBXO45 is notable for its role in the ubiquitin-proteasome system, where it facilitates targeted protein degradation by recognizing specific substrates for polyubiquitination. It is particularly studied in neurodevelopment and cancer biology due to its involvement in regulating apoptosis, cell proliferation, and synaptic plasticity. Structurally, the recombinant version is typically expressed in bacterial or mammalian systems, allowing researchers to study its biochemical properties, substrate interactions, and post-translational modifications in vitro. Studies have implicated FBXO45 in modulating proteins like p73. a p53 family tumor suppressor, and the neuronal protein HYDIN, suggesting roles in tumor suppression and neural circuit formation. Dysregulation of FBXO45 has been associated with neurodevelopmental disorders and certain cancers, though its exact mechanistic contributions remain under investigation. The availability of recombinant FBXO45 enables high-throughput screening for small-molecule modulators and structural studies to elucidate its substrate-binding specificity, offering potential therapeutic avenues for related diseases.
